Flash

From the Super Mario Wiki

Flashes are normal elemental ghosts and a sub-species of the Purple Puncher found in Luigi's Mansion. Ice protects the hearts of these white ghouls. Luigi must melt these ice hearts by capturing a Fire Elemental Ghost and spewing fire at the ghost while avoiding its uppercut. Then the Flash will become vulnerable to the Poltergust 3000.
